Specification of Letters Patent. 77 Patented Feb, 20,1917,

Application filed December 2, 1914. Serial No. 875,089.

To all whom it may concern:

Be it known that I, Monnss S. FINKEL- STEIN, a citizen of the United States, and a resident of New York city, in the county of New York and State of NewYork, have invented certain new and useful Improve; ments in Antirefilling Bottle-Stoppers, of which the following is a specification.

This invention relates'to bottle stoppers, more'particularly stoppers which when applied to bottles render the latter non-refillable.

The principal object of this invention is to provide a stopper of comparatively simple and inexpensive construction which may be applied to any bottle so as to render the latter nonrefillable and thus protect the public from the substitution of spurious or inferior goods by unscrupulous parties, while the dispensing of theliquid from the bottle may be accomplished with ease and despatch.

A further object is to provide a stopper of the above character all the parts of which may be stamped out of sheet metal, easily assembled, and readily applied to bottles so as to remain permanently affixed thereto, their removal being only capable of accomplishment by the breaking of the bottle.

Further objects and advantages arising from the construction, arrangement, and combination of parts will morefully appear from the following detailed description, and the features of novelty will be particularly pointed out in the claims.

, In the drawings,

Figure 1 is a vertical section of my improved bottle stopper shown applied to a bottle.

Fig. 2 is a transverse section taken along line 22 of Fig. 1. I

Fig. 3 is a similar section taken along line 8-3 of Fig. 1. c v p c Fig. 4 is a vertical section of a modified form of my invention also shown applied to a bottle.

Fig. 5 is a view of the form shown in Fig. 4 illustrating the position of the parts in their dispensing positions.

Beferrin g in detail to Figs. 1, 2, and 3, my improved stopper comprises a head 10 provided with a chamber 11. Extendingfrom the edge of the head is an annular flange 12, and suitably secured to thefrange is a closure 13 for the chamber. Aggially depending from the closure is a sleeve 14,

which is provided at its lower end'with an annular flange 15. An outer sleeve 16 envelops the sleeve lah'is of a'length'less than that of the'latter, and is of a diameter such that the sleeve 14 is readily reciprocable therein. The outer sleeve 16 isprovided at its upper and lower ends with annular fianges 17 and 18,respectively. The lower flange '18 is of ,a width such that it falls short of contacting with the neck of the bottle when the stopper is inserted therein. The upper flange 17, however, is of a width to overlap the bead of'the bottle and rest thereon. By reason of the two flanges extending from the outer sleeve 16 there is formed about the latter an annular channel in which may be packed a massof properly prepared cement 19 or other suitable substance when thestopper is to be applied to c the bottle, and after the cement has become hardened and set the stopper will be eiiectually and permanently aflixed thereto, as Will be readily understood.

The upper edge of the inner vsleeve His slightly raisedabove the general level of the closure 13,:and a small annular portion 13* of the latter about thesleeve is also raised angularly from the surface of the closure to meet the edge of the sleeve 14. The edge of the latter is thus comparatively sharp, and therefore constitutes a good seat for the valve head 20 of the valve 21 which is slidably held in the sleeve 14. The lower end ofthe valve is provided with a baffle plate 22.of a diameter preferably greater than that of the valve, and adjacent the baffle plate and valve head the valve is provided witha plurality of ports 23 and 2 1-, respectively. v

The chamber 11 is provided with aplurality of discharge openings 25 formed, at spaced points in the closure 13. These openings are preferably circular, and in order that the chamber may be effectually sealed. while the contents of the bottle is not being dispensed, I form a corresponding number of circular teats 26 in the flange 17 of the outer sleeve which register with the openings and upon which the closure 13 seats. Theteats also serve the further function of preventing the turning ofthe head 10 while the bottles are being-shipped,,This is very important, as .in shipping bottles of this character the stopper and a. portion of the neck adjacent thereto are u 'sually wrapped in tin foil or other similar, ma

terial, and if the stopper were rotatable in- I stead of fixed there would be danger of the foil becoming torn by an inadvertent twisting of the stopper, whereupon the latter becoming released,-the contents of the bottle might spill out.

' As-clearly illustrated in Fig. 1, the ports 24 in the valve are normally out of communication with the chamber 13 as the valve head 2O rests upon the edge of the sleeve 14. The contents of the bottle is, therefore, ef-

fectively sealed from the atmosphere thereby, as well as by reason of the fact that the chamber 11 is maintained. securely sealed as above described.

When the bottle is tilted into its dispensing position the headlO will move forward until the flange 15 in the inner sleeve 14 abuts the flange 18 in the outer sleeve 16. The Valve 21 simultaneously advances until itsvhead strikes the inside surface of the 7 head 10, the valve being of such length that there remains a small opening between the flange 1 5, and the baflleplate 22. The head 10 having advanced clear of the teats, the

ports 24 having moved clear of the sleeve 14, and there remaining an opening between the flange 15 and the baflie plate 22, the liquid in the bottle will have free passage through theports 23, valve 21, ports 24, chamber 11, thence through apertures into the receiving receptacle. Upon being again placed in a vertical position, the vari- The liquid would have to travel by a tortuous route first intothe chamber and then intothe valve and then through the small openings 23 at the lower'end of the valve. This alone would render refilling difficult; but further difficulties are presented. In order to have any possible chance of success in refilling the so-called non-refillable bottles,the liquid must be forced in under pressure. Thus, if a stream of the liquid should succeed in entering the valve when the bottle is kept in an inverted position, the pressure of the liquid upon the baflie plate 22 would cause the valve head 20 to seat upon the-sleeve 14, thus closing the valve. Further, since it is-necessary to provide an outlet for the air contained in the bottle in order that the 'lattermay be filled with the liquid, this proves to be another insurmountable difliculty, for the chamber 11 upon becoming filled with liquid, as it necessarily would under the circumstances, becomes an eflectual seal, preventing all egress of air.

In Figs. 4 and 5 I have illustrated a modified form of my invention, the principle being substantially the same as in the preferred form above described. Thus the head 30, which may be of porcelain or other suitable material, is provided with a circular chamber 31 at its center. An upwardly flaring tube or sleeve 32, terminating at its upper end with an annular flange 33, which is adapted to rest upon the bead of the bottle, communicates with the chamber 31, and is securely embedded within the head 30.

'At the lower end of the tube 32 is formed an annular flange 34. At substantially the junction of the flange 33 and the flaring portion of the tube 32 there are formed a plurality of spaced apertures 35 communicating with the chamber 31. Directly below these apertures a valve 36, having a stem 37 depending therefrom, normally is seated in the tube, this being by reason of the upwardly flaring character of the latter. The

other end of the stem 37 is provided with a circular baflle plate 38 of a diameter preferably somewhat greater than that of the tube 32.

Embracing the tube 32 is a sleeve 39 of a contour corresponding with that of the 9 When the bottle is tilted to its dispensing position, as shown in Fig. 5, the valve 36 moves forward past the apertures 35 and abuts the wall of the chamber 31, the head 30 also moving forward until the flange 34 upon the tube 32 abuts the flange 4-1 of the sleeve 39. The stem 37 being of such length that the plate 38 cannot close the tube 32, the liquid may freely flow up into the latter, through the apertures 35, and into the receiving receptacle.

To prevent the head 30 from rotating, I form lugs 42 upon the flange of the sleeve 39, which register with the apertures 35 and seal the same. However, in this form there could be no trickling of the liquid down the outside of the bottle in any case by reason of any residue of drops in the chamber, as is readily apparent.

In this form of my invention, if attempt were made to refill the bottle by directing a stream of liquid through the tube, the liquid impinging upon the plate 38 would cause the valve to drop below the apertures 35, thus sealing the bottle.

It is clear, therefore, that I have provided a bottle stopper which may readily be applied to any bottle whatsoever and render the same non-refillable. The stopper allows the ready discharge of the contents of the bottle, and when the contents is not being dispensed all openings and ports are effectually sealed, thus preventing evaporation, fermentation, or other deterioration due to contact with the atmosphere. It presents a compact, neat appearance, and does not unduly enlarge the size of the bottle. The head of the stopper, which is all that is disposed exteriorly of the bottle may be embellished in any manner desired so as to 01'- nament the latter It may be all vstamped out of sheet metal, so that the cost of production would be very low.
